In this article, we attempt to analyze the relationship between performance and recession in Taiwanese electronic industry. We apply DEA model to estimate the performance for each firm and then use Wilcoxon signed rank test to examine the relationship between performance and recession. The result shows that: only electronic component has a decreasing trend in revenue during the period of dot-com bubble. On the other hand, the whole electronic industry has a decreasing trend during the financial crisis. Almost all firms have a decreasing performance in two recessions.
